DIANA THERESA against its type
Built in 2009, it is 1 year older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 7,215 gross tonnage it is smaller than 91% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 259 chemical tankers here under the Panama flag, 11.0% of the 2,344 on the register. The returns for 2022–2023 all give Oslo as port of registry.
Its 7,203 t of CO₂ for 2023 is 34% above the median of 5,393 t among the 1,411 chemical tankers on this register that reported for 2023. Per nautical mile it emitted 138.9 kg CO₂, 46% below the type median of 258.0 kg. It logged 4,568 hours at sea against a median of 1,919 hours for its type that year. 4.3% of its 2023 emissions were at berth; the median for chemical tankers was 8.2%. Its efficiency percentile within the type went from 80 in 2022 to 78 in 2023 (lower is more efficient). The one comparable vessel listed below with a 2023 return reported a higher or equal CO₂ per nautical mile.

Efficiency against its own type2023
Position 959 of 1,230 qualifying chemical tankers by EEOI, at the 78th percentile. The dashed line is the type median, 15.6; this vessel reported 27.1.
EEOI divides emissions by transport work, which for this vessel and year was 266,266,543 tonne-miles over 51,869 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2023 was 70.4% higher than in 2022, for EU/EEA voyages only.
From 2022 to 2023, emissions rose 70.4% while distance sailed rose 126.0%and CO₂ per nautical mile fell 24.6%.That points mainly to how much the vessel sailed, rather than the other.
